Definitive Technology DI 6.5LCR In-Wall Speakers

Definitive Technology DI 6.5LCR features Definitive Technology’s Disappearing In-Wall Design. The mounting flange thickness of the in-wall loudspeaker is no more than 2.5mm (0.099″) and is completely covered by the grille that stands a mere 3.5mm (approx 0.145″) from the wall surface. The grille is “micro-perf”, that while presenting an opaque appearance, actually has more open area than typical perforated metal grilles allowing the sound to pass through with less interference and better fidelity. Behind the metal grille is an acoustically transparent proprietary cloth scrim that effectively blacks the dark “shadow” of the black speaker parts from showing through the grille.

Pivoting Aluminum Dome Tweeter with Waveguide

The DI Series in-wall loudspeaker uses Definitive Technology’s proprietary ceramic-coated annealed aluminum 1″ dome tweeter. The DI 6.5LCR tweeter is post mounted, and the tweeter housing is specially smoothed and shaped to use it as an extremely effective low-diffraction waveguide. The aluminum dome tweeter features a pivoting design which allows you to focus the sound toward or away from your listening area depending on the application.

BDSS Drivers

The DI 6.5LCR uses two 6.5″ BDSS drivers for wide-bandwidth accurate frequency response, broad dispersion, low distortion, and maximum detail retrieval. Each 6.5″ BDSS driver cone is supported by specially tuned soft rubber surrounds at both the outer and inner edges. The double surrounds allow the cone to have longer excursion without distortion. As bass output is a function of both a cone’s diameter and excursion, the higher excursion BDSS system brings the benefit of higher bass output from smaller drivers. The DI 6.5LCR’s dual 6.5″ BDSS drivers have the bass output and dynamic range of a typical 10.0″ driver.

Linkwitz-Riley Crossover Network

The Definitive Technology DI 6.5LCR’s second order (12dB/octave) Linkwitz-Riley crossover offers a smooth frequency and phase transition from driver to tweeter for natural midrange response and excellent off-axis performance. A Zobel network flattens the impedance curve of the speaker making it easier for today’s digital amplifiers to drive the speakers. Custom tight-tolerance (+/- 5%) components are used throughout the crossover for superb unit-to-unit performance consistency. Superior metal film capacitors are used in the high-pass section and the Zobel network for extended high frequency response. Oversize inductors (coils) avoid saturation thereby maintaining the wide dynamic range capabilities of the driver.

Environmental EQ

The Environmental EQ switch (on top-frame of speaker) provides a 1dB broad bandwidth tweeter output lift or cut to compensate for highly absorptive or reflective acoustic environments.


The dimpled AeroRings around the 6.5″ drivers are soft Sanoprene rubber and serves several important functions. First, it damps the basket/flange assembly nearest its thinnest part (the flange) to prevent resonance. Second it prevents the grille from rattling in the unlikely event that it makes contact with the speaker frame. It also provides a smooth transition for the waveform coming off the cone. Similar to the dimples on a golf ball that reduce turbulence to aid in longer flight, the dimples on the AeroRing promote smooth “laminar” air flow over the surface thereby reducing diffraction effects. The DI Series in-wall loudspeakers sound clear, natural, and disperse their sound over a wide area.


Definitive Technology DI 6.5LCR Rough-In Bracket – Pair

The Definitive Technology DI 6.5LCR Rough-in Bracket has adjustable arms to attach the bracket to studs or joists before the drywall goes up.


The DI 6.5LCR rough-in bracket is compatible with Definitive Technology’s dual 6.5″ Disappearing In-Wall LCR Loudspeaker (DI 6.5RLCR). DI Rough-in Brackets are packaged two to a carton (2 mounting brackets); mounting screws not supplied.

Metal Brackets

The mounting brackets are fabricated from heavy duty painted stamped steel. There are no sharp metal edges to cut an installer’s hands and they are ultra rigid, so that when drywall is laid over and cut the brackets will not bend or break. The mounting bracket requires rectangular cutout that measures 7.375″ (w) x 16.125″ (h) x 0.375″ (d). The outer dimensions of the mounting bracket are 9.375″ (w) x 18.1875″ (h) x 0.75″ (d).
